I have read several times that Linux users need to install libraries separately (I am Windows user and when I install KiCad I have libraries also installed).
If you have libraries…
As I remember at first run KiCad schematic and PCB asks for libraries giving 3 choices:
default library list,
using file list you show to KiCad,
empty library lists.
I’m sure there are 3 choices (at least in KiCad V8 I’m using), but not sure if one is ‘empty’. May be you selected empty.
KICAD9_3RD_PARTY is for Kicad Resources, Plugins, Colors, etc. It is not for you to place Projects.
If you want your projects in a folder on NASdrive, Open NASdrive, create a folder called My Kicad Projects or whatever and close NASdrive.
Open Kicad go to File > New Project, give the project a name, then on that same “Create new Project” page, navigate to your Projects Folder on NASdrive and Save.
Do this with each new project.
When you wish to work on an existing project, open Kicad, go to File > Open Project, and navigate to your folder on NASdrive. Usually (depending on your OS) Kicad remembers the project you have been working on so there is no need to navigate to your current project.
You need to replace the original path for KICD9_3RD_PARTY. Maybe you will be better off reinstalling Kicad.
What is your OS?
